White began racing go-carts when he was eleven, and has been racing part-time since. Before moving to Busch Series, White dominated the Virginia go-kart circuit. In a five-year stretch, Jason won six Virginia state titles and finished in the World Karting Association top-ten for three different classes of vehicles.

White made his first starts in 1999, running the No. 28 for Larry Lockamy. He started 28th and finished 26th in a solid debut at IRP. He was then 43rd after an early crash at Bristol.

The runs earned him a spot on Felix Sabates' Chip Ganassi Racing No. 82 Chevrolet in a fill-in role in 2000. He ran the Channellock Chevrolet at South Boston, putting in his career best of 21st position. Then, he was 28th at Myrtle Beach.

White next returned in 2002, running a race at Nashville for Frank Cicci Racing. He finished 43rd at Nashville after an early engine problem. Fred Bickford then picked White up for three races, beginning with a 28th-place finish at New Hampshire. His best run came at Nazareth, where he finished 22nd before adding a 37th at Charlotte

White's busiest year was 2003, when he earned 29th in points after a splitting rides at Davis Motorsports and Jay Robinson Racing. He ran mainly for JRR early in the year, finishing a best of 23rd at Gateway. Beginning at Nashville in June, White took over the No. 0 Davis Motorsports Chevrolet full-time. He ran solidly in that race, earning his best career finish of 17th. He would record one other top-20 finish at Pikes Peak, trying to do his best with the low-budget team. White was released following the Memphis race in favor of Kertus Davis.
